Abstract

4-Alkoxyalkyl- beta -carboline derivatives of the formula I <IMAGE> in which R<1> denotes hydrogen or methyl, R<2> denotes a substituted or unsubstituted aliphatic hydrocarbon radical, R<3> denotes lower alkyl and R<A> denotes hydrogen, halogen, COOR<4> or OR<5>, in which R<4> is lower alkyl and R<5> is hydrogen, lower alkyl, cycloalkyl or substituted or unsubstituted phenyl are prepared by reaction with an alcohol of the formula R<2>OH where R<2> has the abovementioned meaning in the presence of AgBF4.
